Question

此查询显示＃1064错误。

DELETE FROM product_price AS pp
WHERE pp.PRODUCT_ID IN (
    SELECT PRODUCT_ID
    FROM (
        SELECT P.PRODUCT_ID
        FROM product p
        WHERE p.PRODUCT_NAME='watch') t
)

Answer 1

使用JOIN而不是像这样的子查询;）

DELETE pp FROM product_price AS pp
INNER JOIN product p ON pp.PRODUCT_ID = p.PRODUCT_ID AND p.PRODUCT_NAME='watch'

Answer 2

在那里't'做什么？试试没有它，像这样：

  DELETE FROM product_price AS pp
  WHERE pp.PRODUCT_ID IN (
      SELECT PRODUCT_ID
      FROM (
          SELECT P.PRODUCT_ID
          FROM product p
          WHERE p.PRODUCT_NAME='watch')
  )
